IBM is offering the public a peek at Bluehouse, an online office portal aimed at making it easier for employees to share documents and desktops, host web conferences, and reach out to clients from one location. Any sized business can sign up to try out the service, though not everything works at the moment. One notably cool feature is the "Live Charts," which does exactly what it sounds like. There's tagging, importing from Outlook or Lotus Notes, and a lot more to fiddle with. Bluehouse is free to use (for the moment), requires a sign-up.
